Are you using a fresh install of rethinkdb?

Some context would be helpful....

[harsha448]

Below is the rethinkdb version which we are using right now..
rethinkdb 2.4.2 (GCC 4.8.5)

We are encountering same error whether i try to use restore command or after extracting the backup dump file and running import command

And do your tables have the needed columns?

Do also the "internal" tables have those columns?

[harsha448]

Yes we do have primary key for the table..Even when i tried with import command ,passing the primary key facing the same error.

Does the problem occur even with https://github.com/BOOMfinity/GoThink ?
